STOCKS | GigaDevice Shares Post Large Gains Over 10 and 30 Trading Days, Company Says

GigaDevice Semiconductor issued an abnormal trading announcement after its stock recorded significant cumulative gains over recent trading periods. According to Odaily, the company said that from June 15, 2026, to June 29, 2026, the cumulative deviation in daily closing-price increases reached 73.42% over 10 consecutive trading days, and from May 18, 2026, to June 29, 2026, it reached 125.60% over 30 consecutive trading days. The company said its current memory products are niche storage products, mainly supplied to broad and fragmented downstream markets outside smartphones, PCs, and servers, including consumer, industrial, networking and communications, and automotive sectors. It said recent price increases for related products were mainly driven by a notable rise in AI-related demand in the mainstream memory market, prompting major international memory manufacturers to shift their business focus toward those products. The company added that the niche storage market has indirectly benefited from tight supply. GigaDevice said that unlike the mainstream memory market, total downstream demand in the niche storage market is relatively stable, and downstream demand has been restrained to some extent during the rapid rise in industry prices. It added that as niche storage capacity increases at the margin, prices are expected to fall by a considerable amount.
